36V/48V BMS 10-14S (11S/12S/13S) 30A/40A/60A Lithium/LiPo 18650/21700 Battery Protection Board — Detection Circuit for 600W/800W/1200W Systems

High-protection BMS for 36V and 48V battery packs designed for 10-14S configurations (including 11S, 12S, 13S). This protection board supports 18650 and 21700 cells and includes a detection circuit to monitor pack status. Safety features: Built-in protections cover overcharge, over-discharge, abnormal high-voltage, and temperature protection (optional). The board also provides discharge overcurrent protection, load short-circuit protection, and charging recovery to prevent damage from electrical faults. Performance: Available models deliver continuous currents of 30A, 40A, or 60A (model-dependent). Balance management is handled with balance currents of 83mA or 56mA (depending on the model) to keep individual cells consistent and extend overall pack life. Compact package sizes to fit different installations: 63×48×8MM, 63×48×14MM, 72×55×8/14MM, or 78×60×17MM (varies by model). The small footprint makes installation straightforward in electric bicycles and electric tools. Applications: Suited for e-bikes and power tools with system power ranges depending on model — compatible with setups up to 600W, 800W, or 1200W. Reliable protection and steady power delivery make these BMS boards ideal for daily commuting bikes and professional electric tool use.
